'Special is generally less useful than normal': this statement sums up Jasper Morrison's guiding principle for creating designs that are 'super normal' rather than extraordinary, showing deference to the dictates of daily life – just like HAL.

Jasper Morrison lives and works in London and Tokyo. His designs are expressions of the 'super normal' design philosophy: rather than seeking unusual or extravagant results, he often breathes new life into proven solutions by means of reinterpretation, further development and refinement. He has worked together with Vitra on a regular basis since 1989.
